Earth could 'flip' into environmental disaster
The study looked back over more than 400,000 years of climate records from deep ice cores and found evidence to suggest that rapid climate change over a period of centuries, or even decades, have in the past occurred once the world began to heat up and ice sheets started melting.
"The unnatural "forcing" of the climate as a result of man-made emissions of carbon dioxide and other greenhouse gases threatens to generate a "flip" in the climate that could "spark a cataclysm" in the ice sheets of Antarctica and Greenland.
Dramatic climatic flips have occurred in the past but none has happened since the development of complex human societies, which are unlikely to survive the same sort of environmental changes if they occurred now."
It has already flipped, contrails, shiptrails, and other trails have , so far, saved the earth. jc

Earth is in imminent peril and nothing short of a planetary rescue will save it from the environmental cataclysm of dangerous climate change, six leading scientists say .
Humanity cannot afford to burn Earth's remaining underground reserves of fossil fuel. "To do so would guarantee dramatic climate change, yielding a different planet from the one on which civilisation developed for which extensive physical infrastructure has been built
